by just going straight out and askingsome girls find it funny or might not say yes when you make someone else askyou would have a better chance asking them in person at least that's what works that most

I second what Mimi-sama wrote. Asking in person gives you the biggest chances and it allows you to immediately clarify every misunderstanding that may take place.And when you want to ask a girl out, try to do it when her friends are not around <- Ning is right. Girls tend to act different in their company.
